The importance of physical training in the game of tennis is already well known. Specialists in the field of sports have done a lot of research and studies on strength programs used in sports training, especially in specific sports: weightlifting, bodybuilding, but for the specific tennis are still few. As a basic component in sports training, physical training has the following objectives: increasing the physiological potential of the athlete and developing biomotor qualities at the highest level to achieve high performance in sports competitions. For the training of the athletes were used numerous physical exercises that involved various jumps from different positions and directions as well as with different loads. The players had a training plan consisting of exercises with jumps on the spot, jumps followed by speed runs, multiple jumps, deep jumps on the gym bench. In choosing the sample of sportswomen, we made sure that they were well prepared physically, without having previous injuries. All tennis players undergoing the experiment are participating in national competitions, being one of the top 100 players in the country in the U14 age category. Since the use of these means in the training of tennis players does not require special equipment, it is very efficient. In all our athletes in our experiment, there was a significant progress for all motor skills, and especially for the one we aim for, strength.
